简介
本篇文章主要目的是为了将用户操作习惯记录到本地文件，然后定期或者根据实际需要打包压缩上传到服务器，用以处理用户在闪退的时候，或需要详细了解具体某个用户在这一段时间的操作习惯。由于要压缩上传本地日志，顺道集成了AFNetWorking了post和get的接口请求，以及请求是接口失败后，错误信息显示，这个在开发的时候特别方便，后台可以在根据这些错误日志查询对应的问题。

一、日志记录集成[LogManager]
在文件中，对每个方法和属性都做了注释；有写入日志方法，也有打印写入日志的方法，以便于检查日志是否成功

打印日志应用实例,在还没引入上传请求接口时，【LogManager.m】文件中可以先将请求接口其注释避免报错：
#import "LogManager.h"
#import "ZMLogView.h"
///显示日志
@property(nonatomic,strong)ZMLogView *logView;
- (void)viewDidLoad {
[super viewDidLoad];
[self testForLocalLog];
}
///写入数据到本地文件并显示
-(void)testForLocalLog{
//写入数据到本地文件
LLog(@"错误信息",@"五哦粗");
//获取日志信息并显示
NSString *str = [[LogManager sharedInstance] readFile:@"2018-09-11"];
NSLog(@"%@",str);
//渲染
[self.logView logInfo:str];
}
#pragma mark - lazyload
-(ZMLogView *)logView{
if (!_logView) {
_logView = [ZMLogView initLogView];
[self.view addSubview:_logView];
}
return _logView;
}
二、使用【AFNetworking】集成接口
1、get请求
/**
get请求
@param url 链接
@param params 参数
@param success 成功代码块
@param failure 失败代码块
*/
- (void)base_GetWithUrl:(NSString *)url parameters:(NSDictionary *)params success:(void(^)(id success))success failure:(void(^)(id failure))failure{
url = [NSString stringWithFormat:@"%@%@",kURLMain,url];
// 创建请求对象
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.requestSerializer = [AFHTTPRequestSerializer serializer]; //设置请求数据
manager.responseSerializer = [AFHTTPResponseSerializer serializer];//设置返回数据
//请求头设置
[ZMBaseEngine setHttpHeaderWithManager:manager];
// 设置超时时长
manager.requestSerializer.timeoutInterval = 10.0f;
//NSString *strUrl = [NSString stringWithFormat:@"%@%@",kURLMain,url];
[manager GET:url parameters:params progress:^(NSProgress * _Nonnull downloadProgress) {
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
//json解析
NSDictionary *dic = [self jsonToDic:responseObject];
success(dic);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
[self handlingError:error failure:failure];
}];
}
2、Post请求
/**
post请求
@param url 链接
@param params 参数
@param success 成功代码块
@param failure 失败代码块
*/
- (void)base_PostWithUrl:(NSString *)url parameters:(id)params success:(void(^)(id success))success failure:(void(^)(id failure))failure{
url = [NSString stringWithFormat:@"%@%@",kURLMain,url];
// 创建请求对象
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.requestSerializer = [AFHTTPRequestSerializer serializer]; //设置请求数据
manager.responseSerializer = [AFHTTPResponseSerializer serializer];//设置返回数据
//请求头设置
[ZMBaseEngine setHttpHeaderWithManager:manager];
// 设置超时时长
manager.requestSerializer.timeoutInterval = 10.0f;
[manager POST:url parameters:params progress:^(NSProgress * _Nonnull uploadProgress) {
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
//json解析
NSDictionary *dic = [self jsonToDic:responseObject];
success(dic);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
[self handlingError:error failure:failure];
}];
}
3、图片上传
/**

@param imgData 图片data
@param fileName 图片名称
@param type 类型
@param url 链接
@param params 参数
@param progress 进度代码块
@param success 成功代码块
@param failure 失败代码块
*/
- (void)base_UpLoadImage:(NSData *)imgData fileName:(NSString *)fileName imgType:(NSString *)type PostWithURL:(NSString *)url parameters:(id)params progress:(void(^)(id progress))progress success:(void(^)(id success))success failure:(void(^)(id failure))failure{
url = [NSString stringWithFormat:@"%@%@",kURLMain,url];
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
// 设置超时时长
manager.requestSerializer.timeoutInterval = 30.0f;
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer =[AFHTTPResponseSerializer serializer];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/html",@"image/png",@"image/jpeg",nil];
[manager POST:url parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {
//上传数据，域名为fileName
[formData appendPartWithFileData:imgData name:@"imageFile"fileName:fileName mimeType:[NSString stringWithFormat:@"image/%@",type]];
} progress:^(NSProgress * _Nonnull uploadProgress) {
progress(uploadProgress);
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
//json解析
NSDictionary *dic = [self jsonToDic:responseObject];
success(dic);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
[self handlingError:error failure:failure];
}];
}
4、文件上传
/**
上传文件
@param url 链接
@param params 参数
@param fileName 文件名
@param upName 上传文件名
@param filePath 路径
@param progress 进度代码块
@param success 成功代码块
@param failure 失败代码块
*/
- (void)base_UpdateFileWithUrl:(NSString*)url parameters:(NSMutableDictionary*)params fileName:(NSString*)fileName upName:(NSString *)upName filePath:(NSString *)filePath progress:(void(^)(id progress))progress success:(void(^)(id success))success failure:(void(^)(id failure))failure{
url = [NSString stringWithFormat:@"%@%@",kURLMain,url];
if (!upName) {
upName = fileName;
}
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
//请求头设置
[ZMBaseEngine setHttpHeaderWithManager:manager];
[manager POST:url parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {
/*
第一个参数:文件的URL路径
第二个参数:参数名称 file
第三个参数:在服务器上的名称
第四个参数:文件的类型
*/
if (filePath&&fileName) {
NSData*fileData = [NSData dataWithContentsOfFile:filePath];
// [formData appendPartWithFileURL:[NSURL fileURLWithPath:@""] name:fileName error:nil];
[formData appendPartWithFileData:fileData name:upName fileName:fileName mimeType:@"application/zip"];
}
} progress:^(NSProgress * _Nonnull uploadProgress) {
progress(uploadProgress);
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
//json解析
NSDictionary *dic = [self jsonToDic:responseObject];
success(dic);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
[self handlingError:error failure:failure];
}];
}
5、请求头/错误处理
///接口请求头

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html", nil];
